  • Patent number: 11678706
    Abstract: Custom-fit versions of knitted articles are produced according to digital representations of objects for which the articles are to be manufactured. The digital representations, optionally augmented by surface fitting algorithms, allow for accurate scaling of pattern-specified stitch counts for pattern elements representing the article taking into account wales and courses densities for the material(s) from which the article is to be made. Displayed dimensionally-accurate representations of the custom-fit articles allow for user-specified style and fit preferences to be made and a final digital pattern of the article to be produced. Machine instructions representing pattern pieces to be knitted are automatically produced from the final digital pattern of the article for a target computerized knitting machine and the custom-fit article then manufactured according to the machine instructions.

  • Patent number: 11329467
    Abstract: A termination arrangement for securing an overhead electrical cable to a dead-end structure such as a dead-end tower. The termination arrangement includes a compression sheath that is configured to be disposed between a strength member and the conductive strands of the overhead electrical cable. The compression sheath mitigates damage to the strength member that may occur when an outer metallic sleeve is compressed around the conductive strands and the conductive strands are compressed against the strength member. The arrangement is particularly useful for securing overhead electrical cables having a composite strength member to a dead-end structure.

  • Publication number: 20140260175
    Abstract: A hybrid rope constructed of a plurality of strands, wherein each strand is constructed of a fiber center, a jacket surrounding the fiber center, and a plurality of wires surrounding the jacket. The fiber center can be constructed of one or more high-strength synthetic fibers or yarns. The jacket can be constructed of polypropylene, thermoplastic polyurethane, high-density polyethylene, linear low-density polyethylene, nylon or other similar materials. The jacket can have a braided or woven design and adds a protective layer between the fiber center and the wires. The wires can be constructed of high-strength steel wires, galvanized steel or stainless steel. The fibers or yarns that make of the fiber center are twisted to lay right and then covered with the jacket. The wires then surround the jacket and are twisted to lay to the left. This creates a torque-balanced condition of the hybrid rope.

  • Patent number: 5683642
    Abstract: A PC strand is formed by twisting peripheral wires made of deformed PC steel wires around a core, and allowing rust inhibitive material of thermoplastic resin to permeate into voids defined among the core and peripheral wires by use of an extruder. Since at least one of the core and peripheral wires is made of a deformed PC steel wire having an uneven outer surface, the thermoplastic resin can smoothly permeate deep into the inside of the PC strand.

  • Patent number: 5335488
    Abstract: A cable is provided for attacking rotating wing aircraft by breaking and/or fouling rotor blades and/or blade pitch adjusting mechanisms. The cable comprises a stretchable core and shallow helix angle outer strands. A high hysteresis rubber or rubber-like material occupies the spaces between the strands and the core. The high hysteresis material prevents the cable from bouncing off the rotor blades when coming into contact therewith.

  • Patent number: 5075952
    Abstract: A method of cladding a reduced diameter portion of a cable wherein the reduced diameter portion is created by grinding the external surfaces of the cable. The cladding is placed around the reduced diameter portion of the cable and is likewise reduced in diameter by rolling, hammering, or other external force. In this manner, a cable cladding can be accomplished without adversely effecting the flexibility of the length of cable.

  • Patent number: 4870814
    Abstract: A process is disclosed for manufacturing corrosion resistant cable. In the process, a corrosion resistant, organic based, alkyl silicate-zinc coating solution is applied to wire as the wire is twisted into cable. The solution dries on the wire in air, leaving an inorganic silicate-zinc coating on the wire. The cable is then coated with a plastic. The process is particularly useful for manufacturing brake cables.

  • Patent number: 4635432
    Abstract: The present invention relates to a method of continuously impregnating and encapsulating a wire rope with a liquid polymer formed from at least two reactive components which when mixed and heated together react chemically to form the polymer. In accordance with a preferred embodiment of the invention, the components are separately pumped into a mixer and then into an injection die, and a preheated wire rope is passed through the injection die. The wire rope is preheated to a temperature sufficient to initiate reaction of the components. The reaction of the components forms the liquid polymer which continuously flows into the voids or spaces of the wire rope and encapsulates the outer surface of the wire rope. The liquid polymer cures in and around the wire rope to form a unitary impregnated and encapsulated wire rope.
